CAMRT Radiography Practice Exam

The 15-degree occipitofrontal view, also known as the occipital projection, is specifically designed to showcase the frontal sinuses and anterior ethmoidal air cells. This particular angle provides an optimal perspective for visualizing these structures by reducing superimposition and ensuring clearer delineation.

In this view, the frontal sinuses are prominently displayed, allowing for the assessment of their size, shape, and any potential pathological changes. The anterior ethmoidal air cells are also featured, which are important in understanding the drainage pathways and the relationships between the sinuses and the nasal cavity. This projection diminishes the overlapping of the adjacent anatomical structures, which might obscure the detailed examination of both the frontal sinuses and anterior ethmoidal air cells.

The other sinus regions, such as the maxillary, sphenoid, and posterior ethmoid sinuses, are not adequately visualized in this specific projection. Hence, focusing on the frontal sinuses and anterior ethmoidal air cells accurately reflects the purpose of the 15-degree occipitofrontal view.
